Hiking Poles

I notice these folks have nice (light 113 grams) three-piece carbon fibre poles which telescope to 50cm thus fitting in your pack when not in use. I managed to lose one of my two-piece poles pushing through thick bush on the Mt Darling Track last week http://www.theultralighthiker.com/snowy-bluff-mt-darling-wilderness/. I was carrying it on the outside of my pack in case my crook knee gave out on me (in which case I could take down my rifle and swap it for a pair of poles). Being longer than the pack, a fork in some regrowth must have fished it out without my noticing, so that now I need to replace it. (Note to self: TIE them in!) I looked carefully on the way back, but did not sight it (probably whipped away off the line of track, I guess): http://www.rutalocura.com/trekking_poles3.html
